Checks the status of continuous backups and point in time recovery on the
specified table. Continuous backups are ENABLED on all tables at
table creation. If point in time recovery is enabled,
PointInTimeRecoveryStatus will be set to ENABLED.

Once continuous backups and point in time recovery are enabled, you can
restore to any point in time within EarliestRestorableDateTime
and LatestRestorableDateTime.

LatestRestorableDateTime is typically 5 minutes before the
current time. You can restore your table to any point in time during the last
35 days.

You can call DescribeContinuousBackups at a maximum rate of 10
times per second.
